Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level. If low, add the recommended power steering fluid.
If the fluid is dirty or contaminated, drain the old fluid from the system.
Refill with new power steering fluid to the appropriate level.

3. Examine Steering Components

Lift the front of the vehicle using a jack and secure it with jack stands.
Inspect the steering linkage (tie rods, drag link) for signs of wear, such as tears or cracks in the boots.
If any components are damaged, remove and replace them as needed.

4. Check Steering Rack

With the vehicle still lifted, manually check the steering rack for any excessive play.
If play is detected, remove the steering rack from the vehicle.
Replace the steering rack with a new or refurbished unit, ensuring proper alignment with the steering column.

5. Tire Inspection and Rotation

Inspect each tire for uneven wear and correct tire pressure as needed.
Rotate the tires if necessary to ensure even wear and extend tire life.

6. Reassemble and Test

Reconnect the battery and ensure all components are securely fastened.
Lower the vehicle and perform a test drive to check for proper steering function.
